REGENERATOR.

SPECIFICATION forming part of Letters Patent No. 606,083, dated June 21, 1898.

Application filed April 6, 1897. $erial No- 680,940. (No model.)

following is a full,clear, and exact description,

reference being had to the accompanying drawings, forming part of this specification,

in whichv 1 v Figure lis a general side elevation of a tilting furnace provided with myimproved regenerators, showing the means for removing and replacing the sections of the regenerators. Fig. 2 is a top plan view of the furnace and connections. Fig. 3 is a sectional detail View of the flue connections, and Fig. 4 is a cross-sectional view showing the construction of the regenerators on a large scale.

My invention relates to the regenerators which are used in connection with melting and other furnaces, and is designed to overcome the difficulty which has been heretofore experienced by reason of the clogging up of the regenerator with deposits of dust, lime, slag &c.

To that end it consists in constructing such regenerators in removable sections which are practically independent of each other and any one of which may be removed and replaced without interfering with the other sections.

It also consists in an improved connectingblock between the ends of the furnace-fines and the regenerator-flues.

In the drawings, 2 represents a tilting open-. hearth furnace supported upon trunnions 3 and having regenerators 4. Each of these regenerators consists of a series of sections which are placed one upon the top of the other over the regenerator-fiues. Each section consists of a casing 5, of plate-steel having riveted thereto angles 6, which give the requisite stiffness, no buckstaves being required. The checker-work in each section is supported upon an arch 7, which is built in the lower portion of the section and carries the weight of the bricks within the lining of the shell. The ends of the shell are provided with annular flanges, by which the sections may be secured together in place, and the sections are also preferably provided with projecting lugs or trunnions 8, which may be engaged by suitable hooks 9, depending from a bar 10, carried from the trolley of an overhead crane 11, by which the sections may be lifted and carried to cars 12 or any other suitable point. The connecting flue-section 13 at the'top of the upper regenerator-section may be made in the same general way as the rege1 1erat0r.'- sections; and may be removed and replaced similarly thereto, these flue-sections connecting with the sections 13, secured to the furnace.

To connect the regenerator-flue to the furnace in case a tiltingor otherwise movable furnace is used, I employ the water-cooled block 14, (shown in Fig. 3,) this block being preferably of wedge form, as shown, and having at its upper end lateral lugs 15 and 16, through'which pass the adjusting-screws 17 and 18, of which the screws 17 rest upon the regenerator-flue and 18.upon the furnace-flue. The block thus hangs upon its lugs, and upon the downward movement of the furnace at one end the block will hang upon the regenerator-flue, whileupon a rise of the furnace it will carry up the block with it.

The advantages of my invention will be apparent to those skilled in the, art, since the troublesome and expensive dust-catchers which have been employed to prevent the clogging up of the 'regenerators may be dispensed with, and when the top section of the regenerator is burned out or clogged up with dust-it may be removed and replaced with a new one with little loss of time. Similarly any of the sections may be changed, duplicates being kept on hand for eachsection. The sections are self supporting and are easily carried about by the projecting lugs or trunnions' The connecting-blocks also are an important part of the invention.

Many changes may be made in the form of the regenerator-sections and their connections, as well as the connecting-blocks, with out departing from my invention, since I claima 1. In a single surface-regenerator, a port= able open-ended section provided in its lower portion with inwardly-projecting supports, said section being filled with a series of separate bricks stacked to form checker-work,

held between the same and having lugs supported upon the fines.

5. The combination with two fines having registering ends, of a block held between the same and having lugs provided with adjusting-screws resting upon the fines.

In testimony whereof I have hereunto set 20 my hand.

JOHN A. POTTER.
